Nutrition and digestion Nutrition is a process which helps the organism to get substances and energy. The Sun is the source of energy of most organisms. Solar energy gets into the body as heat and light. Plants synthesize nutrients in their cells with the help of chlorophills. Plants can get nutrients from the soil and from the air. In the soil the root absorbs water and mineral substances and moves them into the leaves. The leaves use carbon dioxide for nutrition. The green pigments, chlorophills, are in the chloroplasts in the leaves...

Mobility All living organisms move. · Bacteria, single-celled algae move with the help of flagellum. · Protozoa. Amoeba moves with the help of pseudopodia. Paramecium moves with the help of cilia. · Multicellular animals move with the help of muscles. The earthworm moves when the muscles contract: the segments get longer and shorter; the body gets thicker and thinner. Fish move with the help of tail fin. Dolphins and cachalots use their tails to move up and down in water. Some animals move when they react...

Metabolism Metabolism is exchange of substances and energy between the organism and the environment. Plants get water, mineral salts, carbon dioxide and oxygen from the soil; animals get proteins, fats, carbohydrates, water, mineral salts and oxygen from the environment. At the same time plants and animals excrete waste products into the environment. When the substances get inside the organism, they change. E.g. the green plant cells use sunlight to turn water and carbon dioxide into sugars and then – into starch, cellulose, proteins, fats and other substances...
